Experimental Investigation of the Zn-Al-Sb System at 450 °C

Abstract

An isothermal section of the Zn-Al-Sb ternary system at 450°C has been established by equilibrating 11 samples of different compositions and phase identification by optical and scanning electron microscopy with energy dispersive spectroscopy, x-ray diffraction after quenching to room temperature. Five three-phase regions exist in the system at 450°C. No ternary compound has been found. And, the compound AlSb with 2.1 at.% Zn can equilibrate with all phases in the system. Experimental results indicate that the solubility of Sb in a-Al phase is too limited to be detected. The SbZn, Sb 2 Zn 3 , and Sb 3 Zn 4 phases, which have little Al solubility (at most 3.3 at.%), were observed in the system.

“…Because of the importance to the galvanizing industry, the Zn-Al-Sb phase diagram has been investigated by several researchers [18][19][20][21] in the temperature range from 450 to 800°C. Recently, the experimental phase relations and thermodynamic data of this ternary systems at 800°C were determined by Klančnik and Medved.…”

“…Recently, the experimental phase relations and thermodynamic data of this ternary systems at 800°C were determined by Klančnik and Medved. [18] In addition, Zhu et al [19,20] investigated the isothermal sections at 450 and 600°C experimentally and by using the CALPHAD technique. According to Zhu et al, [19] the compound AlSb with 2.1 at.% Zn can coexist with all phases in the system.…”

“…The investigation done by Zhu and others [17] was focused on the region near Al-Zn and Zn-Sb sub binaries at temperature 450 °C. No ternary phases were found.…”
